* '''Up to 50% of ANH can resolve at birth and is referred to as SFU Grade 0 HN.'''

** Many centres will discharge the patient after a normal post-natal US, since the majority of late or recurrent HN are symptomatic and can be counselled as such.
**"it appears contradictory to follow up a documented LGHN within six months, whereas a normal US is followed up within one month."
*'''<span style="color:#ff0000">[In patients with a history of mild to moderate fetal hydronephrosis and a normal post-partum ultrasound (obtained at 1-2 months), additional evaluations are unnecessary.]'''
* '''<span style="color:#ff0000">[In patients with a history of moderate to severe fetal hydronephrosis and a normal post-partum ultrasound, additional evaluations are necessary.]'''
** '''The presence of ureteral dilation on the pre-natal ultrasound has been found to be associated with a significant increased risk for neonatal UTIs and high-grade vesicoureteral reflux despite a normal post-partum renal ultrasound.'''
** A neonatal VCUG is recommended if ureteral dilation is found on the fetal ultrasound.
